In March we went to the Evergreen Museum, which has been on my to-do list since we moved to Oregon.
I am super impressed with the Spruce Goose. I remember it being described in The Aviator movie and seeing it in person was an experience.
Portions of the plane were filled with balls so that it would float when it landed in the water.
The playground was pretty cool too...in the rain it wasn't quite as much fun.
